1.1* Scope. This standard defines types of building construction based on the combustibility and the fire resistance rating of a building’s structural elements. Fire walls, nonbearing exterior walls, nonbearing interior partitions, fire barrier walls, shaft enclosures, and openings in walls, partitions, floors, and roofs are not related to the types of building construction and are regulated by other standards and codes, where appropriate.
A.1.1 It is necessary for the user to consider the influence of location, occupancy, exterior exposure, possibility of mechanical and physical damage to fire-resistant material, and other features that could impose additional requirements for safeguarding life and property, as commonly covered in building codes.
For information on the construction of fire walls and fire barrier walls, see NFPA 221, Standard for High Challenge FireWalls, Fire Walls, and Fire BarrierWalls. For the installation of opening protection, see NFPA 80, Standard for Fire Doors and Other Opening Protectives and NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems.

This standard promotes protection from fire and its associated hazards by defining types of building construction based on the combustibility and the fire resistance rating of their structural elements. It is an extract document of Section 7.2 NFPA 5000®: Building Construction and Safety Code®.
